Cables EP-DRY AL 105 - 8,7/15 kV

Description

EP-DRY AL 105 MT cables are used in isolated power circuits and power distribution substations, industrial and commercial facilities, and can be installed outdoors, in ducts, channels, directly rightly buried in the ground, bank ducts or trays.
While conventional insulated cables for EPR, HEPR or XLPE have a maximum temperature of 90 ° C conductor, EP-DRY AL 105 cables may work with a conductor temperature in continuous operation up to 105 ° C, resulting in a higher current-carrying capacity. Also, they have coordinated insulation thickness, as NBR 6251, with reduced external dimensions compared to conventional insulated wires in EPR HEPR or XLPE.

Notes

Identification of conductors: three-pole cable in the identification of the phases is made by means of narrow ribbon white, black and red, applied over or scoring veins Phase A, Phase B and Phase C on the cover.

Section of the metal shield: for shielded cables section than 6 mm² due to particular conditions of short circuit Phase x Earth or in the case of tinned copper, should be asked specific cable design.

Facilities in conduit: it is recommended that a preliminary study of the occupancy rate and duct material, including induction effects when metal.
